A sample answer to question 1

How would you describe the role of a COO, and how does it complement the CEO?

I see the COO as the person who turns strategy into reliable, repeatable delivery. The CEO sets direction, looks outward to investors, regulators and the market, and shapes culture. My job is to make sure the organisation has the processes, people, systems and discipline to execute, at the right cost and quality, day after day. In practice that means owning operational performance, running the cadence of management reviews, removing blockers between functions and making sure investment goes where it improves delivery. The partnership works best when we are candid with each other, agree who decides what, and present a united front to the organisation. I would also be the person who tells the CEO early when an ambitious plan will not be achievable with current capacity, and then helps work out what it would take to make it so.

Common mistake to avoid: Sounding like a deputy CEO only; Ignoring the commercial side
